'ments ,in Power Driving Mechanism for -motor' and adjuncts;

Computing Type-Writers, of which the following is a specification.

My invention relates to computing typewriters andmy invention consistsin a machine provided with type writing and adding mechanisms, theformer capable of separate and independent operation, means forconnectirig the same for conjoint operation and a motor for operatingthem when joint action is required, and in certain details .ofconstruction substantially as set forth hereinaftter and as illustratedin the accompanying drawings in which:

with adding such as The the movement of writing means with the powershaft Fig. 17 is a detail view showing a part of the sector operatingdevices," Figs. 18 and 19 are face views of two cams for controlling themovements of the sector to operate the adding wheels, the smaller beingthe cam employed for adding one and the larger for adding nine. Fig. 20is a plan view, with the top part of the machine removed, to show thegeneral arran ement of the arts.

The frame A of the machine is suitably constructed to support theoperating parts including the series of keys B, Fig. 1, a motor 'C,carriage D carrying the usual cylindrical platen P, a carriage motor Efor moving the carriage one step on the movement of any key. Thecarriage carries part of the adding mechanism F of any suitablecharacter. As shown a series of number wheels are on the carriage andatoothed sector 224 on the depressing of a starter hereinafter describedis first pushed back and enga es the number wheel opposite it, and thenown to an ex tent necessary to record the number indicated on the keystruck.

The key board is provided with the usual or any suitablenumber oflettered keys 35,

with a series of numeral keys I which are operated by hand as usual intypewriting to print numerals, and with a series of starters H which arenot keys from which the recordingor adding devices are actuated, butwhich serves to set associated parts in position and then make suchconnection with the motor that the proper recording and adding devicesare actuated from said motor. In adding, therefore, the adding andtypewriting devices are not moved by the power applied to the startersbut by the motor C. The typewriting keys are not actuating agents whenthe devices are thus motor operated as the recording devices are.controlled by the] starters and operated by the motor. The? row H asshown also includes keysv which when depressed do not affect the addingonly of the typewriting mechanism, to write certain characters employedin connection 0 and the decimal point. motor C may have the power storedin it om any suitable source but preferably by the carriage as it isdrawn back to position after completing a line; The action of the-motoris communicatedwto. the working. parts through a rockshaft. 1.74

mechanism or motor 0, but operate parts Fig. 3, which extends across themachine and is supported at itsends by the frame of the machine (seeFigs. 6, 7 and 12). the shaft (see Figs. 2 and 3) extends'a series ofparallel a'r'ms 172. The motor O is supported by a' bracket 72 U shapedin plan view secured to one side of the machine frame. The motor has acasing 73 (see Figs. 6, 8 and 12), turning on a shaft 8 8' which issupported in bearings in the bracket 72. A pin98, (Fig. 9) projects fromthe shaft 88 into a key way in. a collar 97 on the shaft A coiled fiatspring 76 is fastened at one end to the collar 97 and at its other endto a pin secured to the casing. A grooved winding drum or barrel 77 isrigidly secured to the back of the casing (Fig. 12) and 'an escapementWheel 78 is rigidly secured to the winding drum77. A hub 89 fits looselyon the shaft 88 and bears against the hub 100, of the winding drum andcarries a ratchet wheel 80 and star wheel 81. A pawl 85 pivoted on theescapement wheel engages the teeth of the ratchet wheel. The .star wheeland ratchet wheel will therefore turn together on the shaft 88. Thenumber of teeth upon the wheels 80 and 81 should be the same.

I To hold the .parts in place the shaft 88-has a shoulder 101 whichabuts against the hub 100, and a washer 95 is fitted on its outer endand is prevented from turning thereon by a pin 102 projecting from theshaft into a groove in the washer. The washer is held against a shoulder103 on the shaft and against the .bracket 72 by a nut 105. The washer isprovided with a series of slots 104 in its edge, and a set screw 96(Fig. 8) passes through one of the slots into the bracket 72, and theshaft and collar 97 are thus prevented from turning under the influenceof the spring 76, but by withdrawing the set screw 96 the shaft may beturned to vary the tension of' the spring and then again secured.

A bracket 145 (Figs. 8 and 1 2)'is supported by the} main frame A andhas downwardly projecting ears receiving pivot pins 139, (Figs. 5 and8). An escapement frame 144 rocks on these pins and carries twoescapement dogs 149 and 150, which swing about the axis of a pin 151.The dog 150 is loose on the pin 151 and the dog 149 is fast to it.

The dog 150 (Fig. .11) has a short tail 161 adapted to engage the faceof the escapement frame when the said dog is in normal.

position with its upper end pressed forward beyond the end of the dog149 by a spring 157 as in Fig. 11. The dog 149 is held normally againstthe face above its pivot by a spring 159 arranged between a tail.160 andsaid face. The dog 149 is normallyv engaged by a tooth of the escapementwheel 78 (Figs. v8, 11v and 12) to then prevent the latter from turning,but when the esc apement frameis rockedfthe dog 149iscarriedlaterallyout of contact with said tooth and 'the dog 150 From.

passes behind said tooth and into position to intercept the followingtooth as the escapement wheel turns in the direction of its arrow (Figs.8 and 11), the up er end of dog 150 being carried backinto a inementwith dog 149, so that when the frame 144 is swung in the reversedirection, the dog 150 144. An adjustable stop 84 'limitsthe rock-' ingofthe said frame,

1 The casing 73, barrel 77, ratchet wheel 80 and the star wheel 81 willmove together under the influence of the spring 76 every time the dog149 is rocked to release a tooth of the escapeinent wheel and totransmit rocking movement to the power shaft. 174 the latter has an arm166 (Figs. 6, 10 and 12) whichhas a roller stud 164 normally resting inthe bot tom of the space between two teeth on the star wheel 81, andwhen the star wheel 81 turns in the direction of the arrow Fig. 10, thecurved side of a tooth, acting as a cam on the roller stud 164, willdepress the arm 166, and thereby rock the shaft 174 and swing. the outerends of all the arms 172 fixed to shaft 174, downwardly. Thereturrrmovement of the power shaft is effectedby a spring 188,

Figs. 10 and 12.

To utilize the return movement of the carriage to wind up the spring 76,the drum of the carriage motor E is connected by a cord or strap 140with the winding drum or barrel of the motor C, and one end of a strap148 is attached to the barrel 47 of the motor E, the

other end of said strap being attached to the typewriter carriagewhereby to drive the carriage step by step, as it is released, in theusual manner. At the bottom of the barrel '47 of the motor E is a boss52, Fig. 13, which has its lower end threaded to receive an arm 53 andon the boss between the arm 53 and the bottom of the barrel turns awinding drum 50, with a peripheral groove, and one end of the cord 140is attached to the drum and passes round an idler pulley 68, Fig. 1, tothe board 77 to which the other end is secured inany suitable manner.The parts are'so arranged that. when the spring 76 is unwound, the cord140 will'be wound on the barrel 77 andloifithe drum 50, and when thecarriage is at its extreme left hand position the strap 148 willbe'wound on the barrel 47and the spring inthe barrel will be unwound.

Thewinding drum '50 is open'at the face:

which is against the bottom of the sprin barrel 47 ,Figs. 1-3 and 15,and it is provide the tendency of this spring is always to turn lockingprojection'147, a cam 6, and ratchet with two annular spaces 91 and71concen- I, The typewriting means and the computcent starter stem andsecure a compact conpressed, it is desirable to look all the other triowith its hub, and in the space 91 is secured a stud 49, Fig. 15, andanother stud 48 secured to the bottom of the barrel 47 projects-intosaid space behind the stud 49. If, therefore, the carriage be moved byhand from left to right the barrel 47 will be turned in the direction'ofthe arrow, Fig. 14 or 15, and the strap 148 will unwind from said barreland by the engagement of stud 48 with stud 49 the winding drum 50 willbe turned to wind the cord 140 on to it and from the drum 77, which willresult in winding up the spring 76 by the movement of the carriageduring which movement the teeth of ratchet wheel 80 will pass the pawl85 which will yield to permit them to do so, and the teeth of theescapement wheel will pass the dog 149 which also yields. The ratchetwheel 80, Fig. .10, is held frictionally a ainst movement, by the camroll .164 normally resting in the space between two teeth of the starwheel 81, where it is hold by the spring 183 connected at its lower endto the arm 166 and its upper end to a pin 182 on the frame, Figs. 6 and10. To maintain the cord 140 taut, a flat spring 75, Figs. 13 and 15, iscoiled in the annular recess 71 in the drum 50, one end of said springbeing connected to a pin 92 in the drum and the other end to a pin 93secured to the winding barrel .47, and

the drum 50 to wind the cord 140 thereon, no matter what maybe thepositions of the barrel and drum relatively to each other.

ing' means and he controller means may be of any suitable character. Asshown each starter stem 1, Figs. 3 and 4, is suitably supported to slidevertically along side of a standard 28. Each starter stem is held in itselevated or normal position by a spring 210, Figs. 6 and-7-,-connectedat the lower end to a clip 211 secured to the starter stem and at itsupper end to' apin 209 projecting from the adjacent standard 28, Figs.6, 7 and 12. The clip 211 is U-shaped to permit the arm' 172 to swingbetween the spring and adjastruction.

As shown in Figs. 2 and 3, the starter stems are fiat and each isprovided with a teeth 2 on its rear edge, and with a rack 262 at itsfront edge and the cam 6 is inclined at its lower end." When one starteris being destarters against depression and this is effected by swinginga bail 11 under the projections 147 of all the starters except the onebeing depressed. The bail 11 is carried by two arms 14, Figs, 4 and 5,which are rigidly connected .to the ends of a rock shaft 9 rocking insupports carried by the main frame. A series of arms 8, one for eachstarter, rigidly l connected to the shaft 9 project forwardly intoproximity with the respective starter stems'just below the cams v6, whenthe starters are in normal position. One 'of the arms 14 is providedwith aprojection 16, Fig. 4,. below the shaft 9 and a spiral spring 20is connected at one end .to the said projection and at the other end tothe main frame, and'holds the arms 8 in the paths of the inclines of thecams and said projection is limited in its movement towards the stems 1by pin 7 with which the projection 16 contacts.- When a stem 1 isdepressed,

upon stem 1 that the arm 8 will not come into contact with the inclineof the cam until the projection 147 on the depressed stem has passedbelow the bail 11 and said cam is of such length that the arm 8 will bemaintained in contact with it during the remainder of the'stroke of thestem. (hi the return of the stem, the arm 8 will leave the cam 6 justbefore the projection147 reaches the bail. It is desirable that thecomputing mechanism shall have a complete,movement at each operation andfor this purpose I provide a pawl .10, Figs. 2 and 3, which prevents astarter, after it has been partially depressed, from rising until themechanism has completed its V movement. The pawl 16 is pivoted at 24 onthe adjacent standard 28,

and its point 29 is normally held in engage--' ment with the rear edgeof the stem 1 by a spring 26 connected at its lower end to the pawl atone side of its pivot 24 and at-its upper end to the standard 28 in linewith the pivot. The pawl is provided with an arm 32 projecting acrossthe stem in position to be, engaged by a pin 33 on the stem on the downstroke, of the latter and by a pin 34 on the stem on its up stroke. Theratchet teeth 2 are so arranged on the stem that the end. of the pawl 10will-not engage them until after the bail 11 has been moved to lock theother starter against depression, after which the pawl will engage theteeth and prevent the return of the starter until after it has completedits stroke. Just before com letion, the pin 33 will strike the arm 32anr throw the lower end of pawl 10 out of engagement with the teeth- 2and the spring 26 swinging to the opposite side of the center 24 willhold it out of engagement, until the pin 34'strikes the arm 32 justbeforethe key lcompletes its upward movement and the pawl wil then bereturned te working position.

The adding wheels, which may be of any preferred form and any desirednumber, in the present case are indicated each simply by a gear wheel247, it being understood that there will be one gear'wheel for everyadding wheel desired and which gear wheels maflthemselves be addinwheels or the supported on a stud 122, Figsa3, 4 and 12,

and has a recess 112 in its edge into" which a pin 11] projects from thestandard 28 and limits the movement of the cam in either direction. Thecam also has shoulders 115 and 116. the latter so located that it willbe struck by the pawl 106 when the stem l-is depressed and the cam willthus the pawl to the extent permitted by the pin 11].. On the up strokeof the stem the shoulder 11,5'will be in position to be struck by thepawl 10S whichwill effect the reverse movement of the cam. The disk 110is held in either of its extreme positions by a spring 125 connected atits lower end to the disk and at its upper end to pm 124 on the standard28.

To insure thatthe motor 0 shall 0 )erate .the typewriting and addingmeans on t e depressing of a starter, the cam disks 110 are providedwith recesses 113 in which lies normally a rod-117 that extends past allthe disks and moves the escapement frame but when any disk 110 is turnedby the pawl 106 on the down stroke of the starter, the rod 117 will beforced downwardly and out of the recesses 113. As this rod extendsacross the machine it will be operated no matter which starter isdepressed, and it is supported at its :ends by two arms 128, 129, Figs.5, 6, 7 and arms therefor guide the sector laterally. A

spring 243 is connected at its upper end to an ear 240 atthe end of thesector arm, and at the lower endto a toe extending from the shaft 134and said spring tends normally to hold the sector in its highestposition, A spring 170 is connected'at oneend to the frame of themachine and at its other end to an ear on the shaft 134 and tendsnormally to pull the upper ends of said arms toward the has beenpartially be turned by be ad ded, and

front of the machine and hold the sector out of engagement with theadding wheels. The function I of the arms 172 is to operatively connectthe separate typewriting'and computing mechanisms to the power shaft 174so that each maybe operated therefrom. There is one arm 172 for eachstarter and the function of said arms is performed in the constructionshown by pullin down a. starter after it e ressed by the opera'torsfinger and in also pulling down the connections of a correspondingtypewriting key 35, for which purpose the arm is provided with a pin 177at its outer end.

As shown in Figs. 2, 3, 7 and 16, each stem 1 has pivoted thereto a hook146 with a rear projection carrying a stud :44. The hook 146 has a tailpiece 199 normally pressed against a fixed stop 39 by a sprin 173, Fig.

16. To the sliding support 300 0 each key 35 is pivoted an arm 37 forkedand'having a book 42 at its lower end, and between theforks extends oneof the studs 44. I When a numeral key used in typewriting, is depressedthe arni 37 will slide up and down reely over the stud 44. When astarter is depressed it carries down the hook 146, and the tail piece199 by its tendency to keep in contact with the stop 39 will cause thehook 146 to swing on its pivot and its lower end will move toward thelower end of the arm 37 with it, thus bringing the book 42 as well asits own hook 146 under the 'pin'177, and when the power shaft rocks, thepin 177 will engage both books carry down starter and the key 35 andconnections and operate both the typewriting and computing mechanisms.

It will be seen that the operations of type writing the fi uresindicating the amounts to of shifting the numeral wheels or other meansfor indicating the sums of said amounts, are not effected by the powerof the operator but are effected from the motorwhich is put intoconnection with the typewriting devices and adding wheels by the act ofdepressing the starter and that this in no way interferes with theordinary operations of the typewriter, the numeral type of which howeverare the means of recording in both cases, that is both by'a motor and byhand operations. It will also be evident that whatever may be the powerrequired to operate the adding means ,the force required of the operatorto actuate thestarter is no greater than that required to operate thetypewriter keys.- i

It will be seen that the starters are not normally type bar actuatin-keys, nor means for actuating the adding devices; but are the means ofeffecting connection of the motor with the 'typewriting and addingdevices.

The sector 224,- Fig. 3, has an elongated pin 177, and carry theopening246 through which a'guide rod 225 extends, said rod being supported bythe wider than the diameter of the rod 225 to permit the' sector to moveinto and out of ensides.

"move with the shaft. v v 222,'Fig. 5, rigidly secured on the shaft 252,

gagement with-the pinions 247, the sides of the slotbeing arcs struckabout the pivot of the sector as a center. On the rod 225 are guidecollars 226, Figs. 3 and 5, which have lips loosely engaging the sectoron opposite One ofv the guides has an extension 230 upon which ispivoted an arm 232 having a lip 250 which engages the side of the guide230 and limits the movement of the arm 232 toward the sector 224 underthe influence of a spring 234 coiled around the pivot of the arm. Thearm 232 is also provided with a laterally extending lip 251 Fig. 5adapted to fit under a pin 229 Figs. 3 and 4 on the sector. The lip 251is beveled on its under side so that when the sector makes its strokeupwardly the pin engaging the beveled sidewill force the arm 232laterally out of its way until it has p'assedabcve it when the arm willswing in below the pin and will support the sector in itsnc-rmalposition. A headed pin 231, Fig.5, limits the outward movement of thearm 232. 7

There is a rock shaft 252 rotatably mounted in the frame, Figs. 3, 5 and7, and rocked at each adding operation, said shaft carryin a series ofarms 215 each having a cam 1'01 217, Fig. 3, at its outer end. The armsThere is also an arm near the middle of the latter, and offset tonot'interfere with the adjacent arms 218 and 219 This arm 222'extcndsalong in close proximity. to the sector and is provided at its outer endwith a slot ".235, Figs. 3 and 5, through which a headed screw 223extends into the sector arm. The arm 222 will thus cause the sector arm.to move up and down with it but thesector arm can move independently toand from the pinions 247.

Upon a stud 256, Fig; 3, projecting from each standard 28 is pivoted acam 241 and a gear wheel 258 is secured to the cam, and the rack 262 onthe adjacent starter stem engages the gear'wheel 258. Each cam has a camtrack 264 extended to form a clearance Slut 265 for the cam roll 217 onthe arm 215. There are nine of the cams, one for each numeral, and thethrow of the cams increases in progressive order, so that the cam'fornumeral nine has nine times as much throw as the cam for numeral one. InFigs. 18 and 19-,

I have shown the cams for one and nine. The cam tracks 264 are such asto bearupon the rolls 217 on op osite sides in'all positlons of the camsand rt. ls, except that there may be small clearances int-he extensions265, and each track extends beyond its effective point in bothdirections. The rolls and therefore the sector, are positively driven toandfrorn all positions both in their operating and return movement, sothat the sector is'posi-.

tion in the cam track 264 as indicated in Fig.

3.. When a starter is depressed, its corresponding cam is caused torotate in the d rection of the arrow, Fig. 18, by theengagementoftherack 262 on the stem with its corresponding pinion 258,but the cam track will be ineffective on the roll 217, exce t to guideit, until'the point 260 is reached, igs. 18- and 19, and the completethrow of the cam is accomplished when the point 261 is reached. Theremainder of the track 264' having its side arcs struck about the pivotof the cam, merely operates to secure the sector against verticalmovement. When a. starter is depressed, it will rotate its cam, and thecam roll 217 and arms 21.5 cooperating with it, will be depressed 'to anextent correspondin to the throw of thecam, and the shaft 252 wi 1 berocked, and-through the arm 222 the sector will be correspondin lydepressed and an adding wheel 247 turne to the extent re' t at ofthestarter depressed. A1 of the cam rolls -217 move up and down togetheruniformly at each operation of the machine and the clearance spaces 265permit all inoperative cam rolls to have this movement although theadjacent cams are stationary.

It will be noted that when the arm composed of pieces 218 and 219 isrocked, the end of the sector arm has a vertical movement at the.pivotal point 221. If the sector arm turned on the screw 223 as afulcrum, it will be evident that vertical movement 1 of the pivotalpoint 221 would ordinarily cause oposite vertical movement of the sector224. t is desirable, however, for smoothness of operation in throwingthe sector mto engagement with the wheels 247 that these ctor shouldmove -,in a horizontal direction only and this is accomplished bycutting the slot 235 at such an angle that the vertical movement of thepivotal point 221 will not lift or de ress the sector end of the arm.

, l Vhile I have described certain parts which are effective inconnection with the power operated typewriting and adding means it willbe evident that some of them'will be qlpired to, add a number corresondmg to serviceable when the operating shaft is moved by hand.

. I have not described or shown the details. of the typewriter mechanismas these may be of any suitable-and ordinary character to secure theproper operation of type carriers shown as bars 220' with relation tothe platen P. I Y

' the latter and returned. If, however,

traverse of the carriage, 1t 1s desired to reated ,to move the points ofall stems In the construction as described, the operation is as follows:Assuming the springs 76 to be wound and the carriage at the right handend of the machine, the typewriting mechanism may be operated as usualwithout affecting the adding mechanism, and the barrel 47 will draw onthe strap 148 and so move the carriage in its step by step movementwithout affecting the position of the drum 50 or drum 73. As many linesmay be rinted as desired without affecting these rums, for the stud 48,Fig. 15, will. move away from the stud 49 and back to it again everytime a line is printed and the carriage at anyperiod in the cord and addfigures, the pro er starter will be de ressed by the finger o theoperator, and t e first resultant action is the partial rotation of acam 241, which is, however,.in-

effective at this stage of its movement. The oint of the pawl 106 nextstrikes the shouler 116 of the cam 110 and rotates the latter,

thereby forcing the rod 117 down out of the recess .113. This results inde ressing the arms128 and 129 and rocking t 1e shaft 134.

The rocking of the shaft causes the upper ends ofarms 218, 219, to swingrearward, thus moving the sector into engagement with the opposed pinion247.- This movement of the sector frees the pm 229 from the lip 251 andthe sector is free to be moved downward. While these movements aretaking place, the hooks of the adding and typewriting mech-' anisms'have swung into position to couple both mechanisms to thepin 177 on thepower arm 172, and the cam 6 on thestem has operbail 11 under thelockingexcept the one depressed, and over the point of the one depressed. Thepawl 10 has also engaged the ratchetteeth 2 and prevents the returnofthe starter until after it has completed its stroke. These are the onlyoperations which result from the act of the operator upon the starterand do not move either the type levers or the adding wheels. After-thecompletion of these various' movements, however, the escapement frame144 will be rocked sufliciently to move the do 149 out of engagementwith the tooth of the escapement wheel, thus releasing the motor, Thestar wheel in turning with the motor rocks the operating print thenumber a ism shown, in so doing pullsjdown the-start shaft 174 whichoperates the adding mechan' ism and also the tygewritin'g mechanism to(1 ed, and, in the mechaners; After the operating shaft begins to act217 to depress its arm 215 and rock the shaft 252, therebv moving thesector downwardly on the adding mechanism, the throwing part of the cam241 will operateon the cam roll and; turning the adding wheels' thefdesired distance.
